UNIFIED METER AND A/C AMP
PFP:27760
System Description
AKS00D5C
●
For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.
●
Unified meter and A/C amp. controls each operation for A/C auto amp. For information regarding A/C con-
trol, refer to
ATC-25, "AIR CONDITIONER CONTROL"
in ATC section.
●
Unified meter and A/C amp. inputs necessary information for combination meter from each unit by CAN
communication and so on.
●
And unified meter and A/C amp. outputs these signals using communication line (TX, RX) between unified
meter and A/C amp. and combination meter.
●
Other input signals are also sent to the ECM, TCM, AWD control unit, BCM, display unit (without NAVI)
and display control unit (with NAVI) using CAN communication.
●
The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (without NAVI) or display control unit (with NAVI)
using CAN communication.
●
The unified meter and A/C amp. have a CONSULT-II function (self-diagnostic results, CAN diagnostic
support monitor, data monitor).

Solution When Communication Error Between the Unified Meter & A/C Amp. and the Combi-
nation Meter
CAN Communication System Description
AKS00D5D
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II BASIC OPERATION
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1.
With the ignition switch OFF, connect “CONSULT-II” and “CON-
SULT-II CONVERTER” to the data link connector, then turn igni-
tion switch ON.
2.
Touch “START (NISSAN BASED VHCL)”.
3.
Touch “METER A/C AMP” on “SELECT SYSTEM” screen. If
“METER A/C AMP” is not indicated, go to

SELF-DIAGNOSTIC RESULTS
Operation Procedure
1.
Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE” screen.
2.
Self-diagnosis results are displayed.
Display Item List
“TIME” indicates the condition of the self-diagnosis results judged by each signal input.
●
Normal: In case of operating properly at the present in spite of having malfunction in the past, then “TIME”
indicates “1-63”.
●
Malfunction: Soon after detecting malfunctions by self-diagnoses or current malfunction, “0” is indicated.
After returning to normal condition, every time when ignition switch is turned to “OFF” from “ON”, time will be
added like “1”
→
“2”
→
“3”···“63”, and when the key operation is performed 64 times, the result of the self-diag-
noses will be erased. And if any malfunction is detected again, “0” will be indicated.
CAUTION:
“TIME” keeps showing “0” after returning to normal condition only in the case that malfunction his-
tory of “CAN COMM CIRC [U1000]” remains because of low tire pressure warning control unit, display
control unit (with NAVI) or display unit (without NAVI) malfunction.
